CASSETTE STRUCTURE

There are three parts to the main balcony structure. Firstly, the Cassette® balconies ‘skeleton’, this in essence, is a chassis which the rest of the aesthetic items fix to. Secondly, the decking above, soffits below, and then balustrade and fascia at the front and sides.


The balcony Cassette® prefinished with decking, soffits, balustrades and fascia’s are delivered pre-assembled. Once a balcony is installed onto the arms, a stirrup style clamp integrated within the Cassette® skeleton is tightened from above. A second anti-slip device is connected to the arms to provide a secondary fixing as a fail-safe.


The cassette itself is made up of 400mm modules, which double up as 400mm drainage trays.


The connection between the cassette and the arms are clamps that act like stirrups, allowing the balcony arm to pass through without hindrance while the balcony is being installed. Once the balcony is in position, the internal installers can easily, and safely tighten these from above and fix down the last boards with the clips.

These clamps have been fatigue tested with 7686 cycles to simulate 60 years of loading.


Decking


With the combustible materials ban anything above 18m must be class A. However even below 18m we'd still recommend a class A deck solution. We mainly use Class A aluminium decking from MyDek (our sister company)


Wood Plastic Composites are the most common deck solutions for class B or C decking. Our go to brand is Enjura, who we are the only UK distributor.


Whilst decking s the most common decking solution, we also have a porcelain solution, seen as a more high end deck solution.


Soffits


Not only are soffits a key design area contributing to the aesthetics of the balcony they also have a number of other key functions.


Our standard soffit is a class A aluminium soffit, which act as the drainage tray, in 400mm modules again, sloping the drainage to the front edge.


Another area where soffits play a very important part is with fire. Balconies not only stop burning embers from falling to the balcony below, they also disperse the heat from a fire below.


Having an aluminium soffit is cost neutral to having no soffit, as with no soffits them internal components within the balcony then require powder-coating,


Other options for soffits are perforated soffits, or no soffits. Both of which should be avoided due to drained through is not a recommended way to go when it comes to drainage.
